As I mentioned many times already, Sy was designed to be a sex slave. There are however many ideas and features that I held back and did not implement due to a lack of time, resource and knowledge. Even though I'm the one who created her, it's an obvious fact that I now understand a lot more about Sy than I originally did. Not all of the concepts behind her are from me, I borrowed a lot of science that I took time to learn and master.
Then the missions came. Then Satie joined the family. And in the end, there were still many ideas I never got to try. One such idea was about to be implemented.
Though Sy can eat, her "stomach" metabolizes all food into energy and there is no waste and no maintenance whatsoever. It's a clean but terribly inefficient system and were she forced to depend on it, it would take ridiculous amounts of food to keep her going. This system exists only so she can occasionally pretend to eat. On certain missions, we might be asked to spend time with other people and eating food helps simulate the illusion of her humanity. Keep in mind that there are other, more personal substances a pretty golden goddess is regularly asked to swallow and I'd rather not have to clean that either.
Long story short, this means that Sy's rectal cavity exists exclusively for sexual purposes. It's a dead end, it's not connected to anything. It's essentially a lovely, tight and self-lubricating hole she owns between her glorious butt-cheeks. When I created her, I planned in advance and carpeted her anus as well as the whole surface of her rectal cavity with sensory input as precise and powerful as the nerve endings at the end of a man's penis. What I did not do however was write code to properly integrate that sensory input to her positronic matrix. Back then, I was really eager to have her with me as soon as I could so, I cut some corners round.
That was my new and latest side-project. Sy could feel when I sodomized her but she did not experience "true" pleasure. I thus planned to correct this deficiency and add more than what was possible with a normal human. I then linked that part of her sensory input to our "intimate wireless" system which meant I integrated a software dimmer that, on the lower end of the sensory spectrum made her feel a normal penetration, procuring her with as much pleasure as any woman taking it in the butt.
Should I choose to set her sensory input to the other end of the spectrum, a mere soft lick on her tight anus and she would go batshit insane with pleasure. A full penetration at that sensory level would send her crashing into an overwhelming maelstrom of delight and pain. I need to re-emphasize the fact that her whole rectal cavity is covered with these sensors.
She's mine. She's my toy and I like to hear my toy scream.
The end of the day had arrived. After a tense supper; Sy was as excited about this project as I was, it was finally time to test it. I took Sy to our playroom and for a few long minutes, we just hugged and kissed as I slowly stripped her of all her clothes.
My sex doll finally in the nude, I turned her around, gently forced her on her knees and tied her up. The best position to test my device was to have her on her knees, legs spread as wide as she could. Her arms were kept above her head, tied by a restraining device that was attached to the ceiling so she was one hundred percent accessible and vulnerable.
I sat in a very low chair just behind her and adjusted her sensory input at about 40% before trying our new mutual plaything.
One thing that was particularly enjoyable about Sy was that, since she wasn't biological, her pubes and her anus were always clean and odorless. Her skin was designed to emanate a faint but pleasant odor to stimulate and comfort the unconscious human need my mind felt but essentially, I could go down on her at absolutely any time and there would never be any surprises. This is why I chose to go head first. Grabbing both her lovely butt cheeks, I spread them to give me a flawless view of her perfectly tight anus and started licking it softly. The result was absolute and immediate: Sy started moaning like a horny slut. I kept at it while and was pleased to see her wiggle her ass to force my tongue to touch her at different spots. The sensor mapping worked beyond my expectations.
I eventually backed up. Again, her reaction was immediate. She looked over her shoulder and gave me puppy eyes as she wailed pitifully, patiently waiting for me to continue the experiment. Very slowly, I inserted a finger as deep as the second knuckle, giving her a superficial penetration. Her moaning was getting a lot louder. I found my desire however to be a lot less intense than what I expected it to be.
I quickly realized that although this project felt very rewarding, I was still thinking about Satie. I loved Sy, there was no denying that, but deep down, it was Satie I wanted tied up here, my manhood deeply entrenched in her round and tight ass. I kept fingering Sy's anus for a few long minutes, her moaning never decreasing. It didn't look like the program was able to solve into an orgasm but that was something I could easily fix later.
It was almost comical. This insanely beautiful, absolutely perfect golden-blonde goddess tied up, completely nude. Her legs spread wide, her enticing temple ready to be taken as brutally as any man could ever like. Yet, the only man in the room sat there, pensively poking her anus as he was thinking about another girl.
And then the door slowly opened. My heart skipped a beat as Satie carefully eked in the room observing us like a curious child. All she wore was a blue-grey velvet babydoll that was a few inches too short for her. She took a few shy steps, entering the room. As she slowly walked, every time her legs uncrossed into her next step, I could catch a glimpse of her soft, earthy-orange pussy. My heart raced and I was forced to admit that soon enough, it felt like Sy was not even in the room anymore.
"What are you doing? Why are you hurting Sy?" She softly asked. Her voice was so tentative, so silky and shy, it made me desire her all the more.
My first reflex was to remove my finger from Sy's anus. As if she had suddenly been released from a long and tiring effort, my android exhaled once and took a deep, cleansing breath.
Sy shifted her torso so she was able to fully face Satie. Her cheeks were flushed with red and she felt out of breath. Those were simulated responses of course. Sy could run one hundred miles and never feel any sort of exertion.
"Satie honey, he's not hurting me! We're playing a game! Would you like to play with us?" Sy's voice was dripping with honey, I had no idea she could sound so motherly and so slutty at the same time.
"I don't want to be tied up!" Satie immediately answered, taking a short step back, fear taking control of her beautiful eyes.
"Oh no, no! We won't tie you up! We play this game using my body so I'm the only one who gets to be tied up. Don't worry sweet baby, I really enjoy it!"
Satie hesitates. "So... what is the game then?"
